| Abstract: | The black soil region of the northeast is an important marketable grain base and a main grain producing area,playing extremely important function on ensuring the grain security of China.The present severe soil and water loss has seriously affected the land productivity and the output of grain.The paper discusses the influence to physical,chemical and biological properties for soil and water loss in black soil region of the northeast systematically and analyzes the main effect of soil and water conservation measures. |
| Keywords: | soil and water loss black soil physical properties chemical properties biological properties soil and water conservation measures black soil region of the northeast |
